Struct VPaddingCell 

pub struct VPaddingCell {
    pub payload: Vec<u8>,
}

Variable-length padding cell.

VPADDING cells are similar to PADDING cells but have variable length. They are used for traffic analysis resistance when variable-size padding is needed.

Wire Format

Variable-size cell:

[ CircID (0) ][ 128 (VPADDING) ][ Length ][ Random Payload ]

Fields

payload: Vec<u8>

Random padding payload.

Implementations

impl VPaddingCell

pub fn new(size: usize) -> Self

Creates a new VPADDING cell with random payload of specified size.

Arguments

• size - Number of random bytes to generate

pub fn with_payload(payload: Vec<u8>) -> Self

Creates a VPADDING cell with a specific payload.

Arguments

• payload - The padding bytes

pub fn pack(&self, link_protocol: &LinkProtocol) -> Vec<u8>

Packs this cell into bytes for transmission.

pub fn unpack(payload: &[u8]) -> Result<Self, Error>

Unpacks a VPADDING cell from payload bytes.

Trait Implementations

impl Clone for VPaddingCell

fn clone(&self) -> VPaddingCell

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VPaddingCell

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for VPaddingCell

fn eq(&self, other: &VPaddingCell) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
